How do ionic and molecular compounds differ in physical properties?
Ionic compounds have higher melting and boiling points than molecular compounds due to the strong electrostatic forces between ions. Ionic compounds are usually solid at room temperature, while molecular compounds can be solid, liquid, or gas. Ionic compounds conduct electricity when dissolved in water, while molecular compounds do not.
What are the difference in conductivity between ionic and molecular compounds?
Ionic compounds typically have higher conductivity than molecular compounds because ionic compounds dissociate into ions in solution, allowing for the flow of electric current. Molecular compounds, on the other hand, do not dissociate into ions in solution and therefore exhibit lower conductivity.
How can you determine whether a compound is ionic or molecular?
You can determine whether a compound is ionic or molecular based on the types of elements it contains. Ionic compounds typically consist of a metal and a nonmetal, while molecular compounds are made up of nonmetals only. Additionally, ionic compounds tend to have high melting and boiling points, while molecular compounds have lower melting and boiling points.
How do you determine if a compound is ionic or molecular?
To determine if a compound is ionic or molecular, you can look at the types of elements it contains. Ionic compounds typically consist of a metal and a nonmetal, while molecular compounds are made up of nonmetals only. Additionally, you can consider the bond type - ionic compounds have electrostatic attractions between ions, while molecular compounds have covalent bonds where atoms share electrons.
How do the formulas differ from molecular and ionic compounds?
Molecular compounds are formed by sharing of electrons between atoms, resulting in covalent bonds, while ionic compounds are formed by transferring electrons from one atom to another, resulting in ionic bonds. Molecular compounds have discrete molecules with defined molecular formulas, while ionic compounds do not have discrete molecules and are represented by empirical formulas showing the ratio of ions present in the compound.

Ionic compounds conduct electricity when dissolved in water, while molecular compounds do not.
How can water dissolve some ionic compounds as well as some molecular compounds?
Water can dissolve some ionic compounds as well as some molecular compounds because of its polarity. It is polar enough to dissolve ionic compounds into their ions. Water does not dissolve molecular compounds by breaking covalent bonds, but through intermolecular forces.

Do molecular compounds boil at a higher temperature than ionic compounds?
No
How are the properties of molecular compounds different from those of ionic cmpounds?
Molecular (covalent) compounds are not dissociated in water.

Is a brittle compound a molecular compound?
No, a brittle compound does not necessarily indicate it is a molecular compound. Brittle compounds can be either molecular or ionic, depending on their chemical bonding. Brittle molecular compounds typically have covalent bonds, while brittle ionic compounds have ionic bonds.
How do the formulas differ from molecular and ionic compounds?
Molecular compounds are formed by sharing of electrons between atoms, resulting in covalent bonds, while ionic compounds are formed by transferring electrons from one atom to another, resulting in ionic bonds. Molecular compounds have discrete molecules with defined molecular formulas, while ionic compounds do not have discrete molecules and are represented by empirical formulas showing the ratio of ions present in the compound.
How are the melting points and boiling point of molecular compounds different from ionic compounds?
Molecular compounds typically have lower melting points and boiling points compared to ionic compounds. This is because molecular compounds are held together by weaker intermolecular forces (such as Van der Waals forces) compared to the strong electrostatic interactions in ionic compounds.
How do ionic compounds and molecular compounds differ in their relative melting and bioling points?
Ionic compounds tend to have higher melting and boiling points compared to molecular compounds. This is because ionic bonds are generally stronger than the intermolecular forces present in molecular compounds, such as van der Waals forces. The strong electrostatic forces between ions in an ionic compound require more energy to overcome, leading to higher melting and boiling points.
How are molecular compounds different from an ionic compound?
Molecular compounds consist of covalent bonds formed by sharing electrons between atoms, while ionic compounds involve the transfer of electrons from one atom to another, resulting in the formation of positive and negative ions. Molecular compounds typically have lower melting and boiling points compared to ionic compounds and are often composed of nonmetals. Ionic compounds tend to have higher melting and boiling points, are composed of metals and nonmetals, and form crystalline lattices.
